Define custom root json node on ember serializer

I'm trying to get brands items from my REST API with ember; but my API response does not match with ember-data expected. for example:

My model:

import DS from 'ember-data';

export default DS.Model.extend({
    name: DS.attr('string'),
    isActive: DS.attr('boolean')
});

My API url: http://localhost:3000/api/brands its response with:

{"success":true,
     "data":[
        {"id":1,"name":"Mine","isActive":true,"createdAt":"2017-04-23T20:36:49.000Z","updatedAt":"2017-04-23T20:44:32.000Z"},
        {"id":2,"name":"forever","isActive":true,"createdAt":"2017-04-23T20:41:14.000Z","updatedAt":"2017-04-23T20:43:57.000Z"}
    ]
}

but, Ember is expecting some like this:

"brands": [{

    "id": 1,
    "name": "foo",
    "isActive": "foo"

}]

I'm trying to change the root json node in serializer called brand.js, but I can not make it work. :(

here my serializer/brand.js

import DS from 'ember-data';

export default DS.RESTSerializer.extend({

});

and my adapters/application.js

import DS from 'ember-data';
import DataAdapterMixin from 'ember-simple-auth/mixins/data-adapter-mixin';
import config from '../config/environment';


export default DS.RESTAdapter.extend(DataAdapterMixin, {  
    host: `${config.host}`,
    namespace: `${config.namespace}`,
    authorizer: 'authorizer:custom'
});

on browser console this message appears:

WARNING: Encountered "success" in payload, but no model was found for model name "success" (resolved model name using vanely-web@serializer:brand:.modelNameFromPayloadKey("success"))
WARNING: Encountered "data" in payload, but no model was found for model name "datum" (resolved model name using vanely-web@serializer:brand:.modelNameFromPayloadKey("data"))

How can I say to ember where the correct data is?.Some help is appreciated.

Sorry if my English is not well.
